Hi Antonio,

=C2=A0

You need= to change the BIOS parameter =E2=80=9CL3 Cache as NUMA Domain=E2=80=9D to = =E2=80=9CDisable=E2=80=9D.

With thi= s, each L3 cache will not be reported as a NUMA domain (/NUMA node). =C2=A0=

=C2=A0

Thank you!=

Subject: AMD NPS bios change is is not reflected onto NUMA domains d= etected by DPDK 21.11

=C2=A0

Using an=C2=A0 AMD EPYC 7713 64= -Core Processor (there are two on the server) for a total of 128 cores.=C2= =A0

=C2=A0

If I change the NPS (numa per s= ocket) in BIOS and power cycle the system and the I launch a DPDK applicati= on, I always get this message:

=C2=A0

EAL: Detected CPU lcores: 128 EAL: Detected NUMA nodes: 16

=C2=A0

NPS is able to change the numbe= r of NUMA but DPDK always detects 16 NUMA domains.

I tried with NPS1, NPS2, NPS4.<= u>
